Build gone but picture on the world map still showing

So, I have a building only save file, that I regularly use. Now, after having saved the build before, whenever I load into it, the house is replaced by the Sims 4 default one. I would chalk it up to being mistaken in having saved, but beside the fact that the time of the save files is correct, the picture of my previous house shows up on the World map. I tried to repair, to load in without mods and clear the caches.

Please help, I don't even know how it could've happened since I didn't even use mods on that build.
